Comparison of short-term and long-term efficacy of minimally invasive surgery and medication for early primary frozen shoulder / 中国内镜杂志

ABSTRACT

Objective To compare the short-term and long-term efficacy of minimally invasive surgery and medication for early primary frozen shoulder (PFS). Methods 82 patients with PFS from June 2014 to September 2015 were enrolled in the study and randomly divided into drug group and operation group, 41 cases in each. Patients in drug group were given steroid hormone intraarticular injection therapy while in operation group, patients were given arthroscopic clearance and release for glenohumeral joint and subacromial space. The baseline data, scores of visual analogue scale (VAS) and constant shoulder joint, active range of motion (ROM) of internal rotation, external rotation, abduction and flexion. Results There were no significant differences in baseline data, scores of VAS and constant shoulder joint, active range of motion (ROM) before treatment between the two groups (P > 0.05). Compared with them before treatment, the VAS scores of the two groups decreased significantly after treatment while constant shoulder score and active ROM increased significantly (P < 0.05). At 4 weeks after treatment, VAS scores in operation group was significantly higher than that in drug group, constant shoulder score and active ROM was significantly lower than that in drug group (P < 0.05). At 12 weeks, 6 months and 1 year after treatment, VASscore in the operation group was significantly lower than that in drug group, constant shoulder score and active ROM was significantly higher than that in drug group (P < 0.05). Conclusions Arthroscopic minimally invasive surgery and drug injection are all effective treatments for early PFS patients. The short-term efficacy of drug injection was significantly better, but the long-term effect was poor. Instead, the long-term effect of minimally invasive surgery was more prominent, and combined with oral drugs and postoperative rehabilitation could significantly improve shoulder joint function and the quality of life, which is worthy of promoting clinical application.
